Machine for producing lines and marks



July 8, 1930. F. R. ALLEN MACHINE FOR PRODUCING LINES AND MARKS FiledFeb. 8, 1926 INVENTOR MJL-N 4 ATTORN Patented July 8, 1930 UTE STATESFRANK R. ALLEN, F PASSAIG, NEW JERSEY MACHINE FOR PRODUCING LINES ANDMARKS Application iled February My invention relates to improvements inmachines for producing lines and marks.

The object of my invention is to provide a simple and convenient machinewhereby lines or marks may be made upon a surface.

The best mode in which I have contemplated applying my said invention isillustrated in the accompanying drawings in which:

Figure 1 is a side elevation of the device,

Figure 2 is a vertical section of the same on the line 2-2 in Figure 1,

Figure 3 is an isometric view of the device, and

Figure el is an optional form of the peripheral marking brush.

Similar characters of reference refer to similar parts throughout theseveral views.

My improved device includes a cylindrical tank 1 provided with an axle2, by which it may be rotatably mounted on any convenient carriage. Thecylindrical wall 3 of tank 1 has peripheral discharge aperturesltherein.

Circumferential flanges 31, 4:1 are preferably provided along the sideedges of the wall 3. Abutt-ing each flange 31, 4:1 and surrounding thecircumferential wall 3 are a pair of rings 8, 9 preferably of rubber.These rings are rectangular in cross section.

A compressible absorbent pad or shoe 5 is arranged upon the cylindricalwall of the tank 1 between the rings 8, 9 and may be detachably securedthereon by means of pins 6 and 7 inserted through its ends and the rings8, 9. rIhe pad or shoe 5 is of greater thickness than the rings 8, 9 andtherefore extends beyond the circumference of the rings.

One side 11 of the tank 1 is preferably detachable to permit accesstothe interior of the tank 1 for cleaning and is secured thereon bymeans of bolts 12, 12 inserted therethrough and secured in ears 13, 13or the like on the wall of the tank 1.

Marking fluid is supplied to the tank 1 at the supply port 10 and, byreason of the peripheral discharge apertures 4, will saturate theabsorbent pad or shoe 5. As the tank is rolled over a surface to bemarked, the bv' marking fluid will be deposited or impressed 8, 1926.Serial No. 86,773.

upon the surface by the absorbent pad 5 which will be compressed by theweight of the tank 1 until the rings 8. 9 are in Contact with thesurfacewhereby the marking fluid will be pressed out of the pad. Thispad 5 is preferably of a resilient nature which will expand when thepressure or weight of the tank is removed and will draw into itself themarking fluid as the point of pressure is passed. rlfhe rubber rings 8and 9 at the sides of the absorbent pad or shoe will serve to limit thespread of the marking fluid laterally beyond the area which it isdesired to cover.

An optional form of marking shoe is illustrated in Figure l. In thisform of the device, I provide a suitable fabric or the like 14 carryingbristles 15, upon the periphery of the tank 1, in place of the absorbentshoe 5, above described. The other parts of the device being as aboveexplained and specified. P

In this form of the device, the marking fluid is discharged through theperipheral apertures 16 and is spread by the bristles 15. AV cut-0E orsliding valve is preferably provided in this form of the device and maycomprise a cylindrical cut-ofi' plate 17 having apertures 18 whichnormally register with the apertures 16 of the tank 1 when the device isin use, but which may be moved or rotated to close the apertures 16 whenthe dcvice is not in use. This form of the device is adapted for usewith a heavy marking fluid or paint. The cut-oli1 valve may, however, beused in either form of the device as conditions may require.

Having thus described my invention, what I claim is:

1. In a device of the character described, the combination of acylindrical tank having peripheral discharge apertures therein, acompressible shoe on the periphery of the tank adapted to be permeatedby a fluid contained in the tank, a cylindrical cut-0E plate within thecylindrical tank having apertures therein adapted to register with thetank apertures, said plate being rotatable within the tank to cut olfflow of fluid to said tank apertures and rings at the sides of the saidshoeJ normally disposed below the plane of the surface of the said shoeand adapted to limit the area to be covered by the said fluid.

2. A device of the character described comprising a cylindrical tankhaving end closure means, the cylindrical Wall of said tank havingvapertures therethrough, circumferential side flanges on said Wall, ashoe adapted to be'permeated by a inid in said tank and surroundingtheWall of the tank, and :rings at the sides of said Vshoe and between saidshoe and said flanges normally disposed below the plane of the surfaceof the said shoe vand adapted to limit the area to be covered by saidfluid. f

3. A device for producing lines comprising a cylindrical tank, means to'support said tank for rotation, said tank having circumferential sideflanges, spaced rings surrounding said tank and laterally abutting saidflanges, a shoe circumferentially surrounding said tank between vsaidrings and normally extending beyond the vcircumference of said rings,and means to lock said shoe tosad rings. f i

In testimony whereof I aix my signature.
